GM1 SIMD.200 Substantiation of the scope of the validation source data ED Decision 2014/033/R (a) The substantiation of the scope of the validation source data (VSD) should be performed by: (1) demonstrating that the applicant has developed and used a process that is acceptable to EASA (see point b of [GM1 SIMD.100](#_DxCrossRefBm1279459506)) to develop the scope of the VSD; (2) using a list of parameters to be recorded for the different validation tests; the proposed validation data (VD) should be presented in a way that allows EASA to verify by analysis that that VD is suitable to fulfil the requirements of CS-FSTD(A) or (H): (i) before initiating the VD gathering campaign, the data providers should have suitable supporting documentation for all necessary flight tests indicating aircraft configuration, flight conditions, piloting techniques, associated CS-FSTD test requirements, etc.; aspects such as data acquisition equipment type, installation, sampling rate, etc., should also be described as part of the flight test data gathering process; such documents should also constitute the basis for the data provider processes to verify the quality and suitability of the collected data before it is submitted to EASA; (ii) whenever snapshot validation is considered in the associated CS-FSTD objective test, the proposed snapshot test points should be obtained during a continuous uninterrupted flight to avoid unexpected changes in aircraft configuration (weight, CG, etc.) or flight conditions such as wind; and (iii) each data parameter should be clearly described and labelled together with its unit; providing only software or data acquisition variables is not acceptable; (3) assessing the adequacy of the proposed VD and the associated validation data roadmap (VDR) by observing the first evaluation of the first type-specific FSTD (see [GM3 SIMD.200](#_DxCrossRefBm1279459507)); or (4) alternatively, in any other way that may be proposed by the applicant and agreed by EASA. (b) An additional set of validation tests may be specified to complement the minimum set of validation tests that are listed in CS-FSTD(A) or (H) (‘Table of FSTD validation tests’). A typical illustration of such possible additional specifications may be the following: the behaviour of the aeroplane on ground at 95 % of maximum crosswind should be simulated with the associated VD. In this example, the minimum would normally be 60 % of the aeroplane flight manual (AFM) value. (c) Based on the technical verification performed at the data provider and a theoretical compliance check of the presented VDR against the applicable regulations, EASA assesses the adequacy of the VDR and associated VD to establish if an initial evaluation can be envisaged. However, the result of the first evaluation of the first FSTD may lead to an update of the proposed VDR (see GM3 SIMD.200). Subsequently, the updated VDR becomes the basis for the qualification of FSTDs for that type of aircraft. [Issue No: SIMD/2]
